The Lowdown
Alright, Rusty here again. Let’s break it down in feet and miles per hour.
We’ve got a solid run of surf on the cards for Jaconé, though it takes a little while to really fire up. The first few days are a bit of a mixed bag – some clean windows, but the swell’s not massive. The real magic starts to build as we head into August, and there’s a standout session that’s got me pretty excited.
Kicking off Saturday morning, 25 July, it’s glassy with a light NNW breeze and a 5ft S swell wrapping in at 10 seconds. The wave energy is moderate (444), and it’s clean. That’s a good start. The water temp is about average for this time of year, so nothing wild there. By the afternoon, the wind swings onshore and it gets messy, so get your session in early.
Sunday morning, 26 July, has a smaller 3ft S swell, but the period jumps to 14 seconds – that’s a long-period groundswell with solid energy (602). The wind is cross-onshore though, so it’ll be a bit bumpy. Not the cleanest, but there’s grunt in the water.
Monday, 27 July, brings offshore ENE breezes in the morning with a 3ft S swell at 12 seconds. Energy is moderate (378) and conditions are clean. It’s a fun, small wave day. The afternoon gets a bit windier but still rideable.
Tuesday 28 and Wednesday 29 see the swell drop to 2-2ft, but with light offshore winds in the mornings, it’s clean. The energy is weak (213-240), so you’re hunting for the little peaks. Fine for a longboard or a fish.
Thursday 30 July is a write-off – onshore winds and a small, weak swell. Friday 31 July is glassy in the morning, but the swell is tiny (2ft) and energy is very low (93). Not much to write home about.
Now, things start to pick up on Saturday, 1 August. Morning offshore NE wind, 4ft S swell at 11 seconds, and moderate energy (376). It’s clean and punchy. Sunday 2 August is a bit smaller but still clean with offshore winds.
Here’s where it gets good. Monday, 3 August, morning has a 4ft S swell with a long 13-second period and clean conditions. Energy is moderate (432). The standout, though, is Tuesday, 4 August. Glassy conditions in the morning with a 5ft SE swell, 10-second period, and strong wave energy (678). The forecast says “expect very good surf conditions” – and I’m feeling it. The afternoon stays clean with a 6ft SE swell. This is the pick of the first week.
Wednesday, 5 August, sees a moderate offshore wind with a 5ft ESE swell, but the wind is a bit stronger. By Thursday, 6 August, we’ve got a 7ft ESE swell on Thursday morning with offshore NE winds – that’s got some serious energy (759) and is clean. The afternoon swells to 8ft, but the wind cranks up to 35 km/h cross-offshore, so it’s going to be bumpy and only for the experts if you paddle out.
Friday, 7 August, is another good one – morning offshore with a 6ft ESE swell, moderate energy (673), and clean. The weekend of 8-9 August keeps the swell pumping. Saturday, 8 August, morning has 6ft E swell with light offshore NE winds. Sunday, 9 August, is the big one: an 8ft ENE swell coming in at 9 seconds, with light offshore NNE winds. The wave energy is very strong (1355), and it’s marked as “excellent surf conditions for experienced surfers.” This is a serious session – definitely not for beginners. The 8ft+ size and short period will make it dumpy and powerful, perfect for the crew who know what they’re doing.
Overall, the standout sessions are Tuesday, 4 August, for the combination of glassy conditions, clean surf, and solid energy, and Sunday, 9 August, for the raw power and clean offshore wind.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
